Acoustic Stealth Detection - Less Detectable Noise Footprints

Acoustic stealth and acoustic discretion play a vital role in submarine operations.
Brüel & Kjær supplies systems for acoustic ranging of submarines and surface ships, for noise source investigation during design and build and for self-monitoring during operations.
Above the water and up in the skies, UAVs are playing an increasingly important defensive role, and have needs – just as with submarines - to be less detectable. Noise footprint assessment and noise characterization are important. Brüel & Kjær designs and builds arrays for noise source identification.

  • Noise source investigation during design and build
  • Self-monitoring during operation
  • Noise footprint analysis
  • Noise source identification
  • 3D noise mapping
  • Underwater acoustic ranging

Durability Testing Systems

Noise/Vibration Detection and Shock Testing SystemsFor any aircraft, helicopter, space vehicle or ballistic device, reliability is the number one priority.

By using our noise/vibration detection and shock testing systems, transducers and high-speed data acquisition systems, a product’s reliability and integrity can be proven.

  • Accelerated lifetime vibration testing
  • Fatigue testing
  • Climatic simulation
  • Package testing

Engine and Gearbox Monitoring

Engine and Gearbox Monitoring

Stringent engine and gearbox monitoring through vibration analysis of rotating machinery provides valuable information on engine health, reliability and performance.

Brüel & Kjær HUMS (Health Usage Monitoring Systems) transducers are permanently mounted on gearboxes of civilian and military helicopters. Our vibration measurement and analysis solutions are found in both test-cell applications and on-ground maintenance systems.

  • Test-cell applications and on-ground checks
  • Balancing
  • Vibration diagnostics using real-time analysis
  • HUMS transducers

Structural Dynamics - Analysing Structures

Structural Dynamics - Testing of StructuresStructural dynamics and the testing of structures is essential to understand and optimise the inherent dynamic properties of structures to ensure reliable and safe operation.

Brüel & Kjær's structural test suite offers complete solutions for controlled excitation testing, real-life operational testing and test-FEA integration from the smallest components to the largest assembled structures.

  • Controlled excitation testing
  • Classical and Operational Modal Analysis
  • Operational monitoring, testing and troubleshooting
  • Virtual model validation
  • Operational Deflection Shapes
